One of NASCAR’s most popular drivers and one of racing’s biggest stars, Patrick filed for divorce in the Superior Court of Arizona in Maricopa County, according to documents obtained by Sporting News.

Arizona is a no-fault divorce state, requiring no reason for a divorce. The divorce cannot be finalized for at least 60 days from the time Hospenthal is served with the divorce papers, and Hospenthal will get an opportunity to respond.

Patrick stated in her filing that the couple have a prenuptial agreement, that neither side will require alimony and that they will present a settlement agreement to the court at a later date. They have no children and there have been no incidents of domestic violence, according to the filing.

“My marriage is irretrievably broken and there is no reasonable prospect of reconciliation,” Patrick stated in her filing.

A Patrick spokesmen said she would have no comment on the filing.

“I’ve always been very private about my private life and I’m going to keep it that way,” Patrick said on HuffPostLIve last November.

Hospenthal, who is 17 years older than the 30-year-old Patrick, is a physical therapist and met Patrick while treating her for an injury.

“I am sad to inform my fans that after 7 years, Paul and I have decided to amicably end our marriage,” Patrick said in a Nov. 20 post on her Facebook page.

“This isn't easy for either of us, but mutually it has come to this. He has been an important person and friend in my life and that's how we will remain moving forward."

Patrick, whose third-place finish in the 2009 Indianapolis 500 was the highest finish for a female in that event, will be a Sprint Cup rookie this season for Stewart-Haas Racing.

She ran three seasons in the NASCAR Nationwide Series. She finished 10th in the Nationwide standings last year, becoming the first female driver to finish in the top 10 in a NASCAR national touring series last year.
